What is the emf through a single coil of wire if the magnetic flux changes from -57 wb to +43 wb in 0.17 s? o 588 v o 344 v o 386 v o 496 v

Emf through a single coil of wire is 588 V.

Explanation:

We need to find the emf through a single coil of wire if the magnetic flux changes from -57 Wb to +43 Wb in 0.17 s

According to Faraday's law, emf of coil is directly proportional to the rate of change of magnetic flux. It can be written as :

Initial flux,

Final flux,

So,

or

So, the EMF through a single coil of wire is 588 V. Hence, this is the required solution.
